WlNDLASSlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 555,521, dated March 3, 1896.

Application filed August 17, 1895. Serial No. 559,616. (No model.)

My invention relates to a windlassing-machine designed for closing in the ends of barrel-staves preparatory to applying a hoop or hoops to one end of a barrel; and the object of my invention is to provide a machine for this purpose which shall be adequate for heavy work and which shall be practically continuous in operation, giving the operator sufficient time for applying the hoop or hoops and for replacing the barrel for another operation and which shall utilize the gravity of the main operative cams of the machine to assist the power in performing the work.

Reference is to be had to the accompanying drawings, forming apart of this specification,

in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of my new and improved windlassing-machine, and Fig. 2 is a front elevation of the same.

A A represent the two side plates or standards of the frame ofthe machine, which side plates or standards are securely united at their upper ends by a table B. The said table B is recessed at one edge, as shown at B, Fig. 2, to partially inclose the barrel 0, which is supported upon a suitable stool, table, or other support D, sufficient in height relatively to the length of the staves and the height of the machine to hold the ends of the staves slightly above the said table B, as shown clearly in the drawings. In the said side plates I or standards A A is journaled a heavy shaft E, to which are secured two large gear-wheels F F and also two heavy eccentrics or cams G G. The said gear-wheels and-cams are re-' volved by another shaft, H, pinions h it thereon, and an end gear 72,, which latter gears with another pinion, 72. on a short shaft h to which the band-wheel H'is secured, as shown clearly in Fig. 1. 4

J J represent sliding blocks'fitted in ways A A, formed in the side plates or-standards A A beneath the shaft E; These sliding blocks are each formed with'a proj ectionj, which projections reach into the sweep of the cams G G,

so that the said blocks and projections will be depressed with great force by the action of the cams. To the'said sliding blocks are secured by clamps 7c the ends of the windlassing-rope K, which is of suitable length in the slack to pass around the staves when the said sliding blocks are elevated to the limit of their upward movement, as shown clearly in Fig. 2. When the said sliding blocks are depressed by the cams G G to the limit of their downward movement, said rope K will have drawn in the ends of the staves ready to have a hoop or hoops placed upon them by the operator. The said Windlass-rope K passes over pulleys L L, journaled at the edges of the table B, and said table and the upper ends of the standards A A are recessed, as shown at a I), respectively, to clear for the said pulleys, as will be understood from Fig. 1.

The sliding blocks J J are elevated by weights M, attached thereto by ropes or cords N, which pass over pulleys N, journaled at the ends of the table B, as clearly shown in Fig. 1.

The cams G are duplicates and are each formed with an eccentric face g, which reaches approximately from the shaft E to the center of the cam, as indicated at the point d, from which last-mentioned point to the end d of the cam the face 9 thereof is concentric, so that the cams will act first to depress the sliding blocks to the limit of their downward movement, causing the windlassing-rope to close in half-revolution of the said gear-wheels F and the cams the operator is given ample time to replace the barrel with another to be closed in and hooped, so that there need be no interruption of the continuous rotation of the machine. The said cams G are necessarily very heavy, and in order to utilize their weight to assist in performing the work, and also to cause them to act as governors to obviate racing or irregular movement of the machine, I attach them to the shaft E so that their mediate points (1 will be on a horizontal plane, or nearly so, with the shaft E when the cams begin their depression of the sliding blocks J. In this manner the weight of the cams assists the turning of the machine and the performing of the work, and after the outer ends cl of the cams pass the sliding blocks the weight of the cams acts to retard the turning of the machine, and thus serves to govern its action during that part of the revolution when no work is being performed.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1'. Awindlassing-inachine,constructedsubstantially as herein shown and described, the same consisting of the main standards provided with vertical channels or ways, a table attached to said standards, a main horizontal power-shaft journaled in said standards, gear-wheels, and two eccentrics, or cams, secured on said power-shaft to rotate in vertical planes, combined with a pair of verticallysliding blocks fitted in said channels or ways, and provided with projections which reach into the plane of the sweep of the said eccentrics, or cams, a windlassing-rope attached at its opposite ends to said sliding blocks, and weights attached by ropes or cords to said sliding blocks for elevating the same and for slackening the windlassing-rope, substantially as described.

2. A windlassing-machine, comprising in combination two main standards formed with vertical channels, or ways, a table attached to said standards, a main horizontal powershaft journaled in said standards above the said channels or ways, a pair of large gearwheels, F, secured to said shaft adjacent to the said standards, two cams, G, secured to said shaft between the said gear-wheels, F, and the said standards, a pair of verticallysliding blocks fitted in said channels, or ways, beneath the power-shaft, and beneath said cams, and provided with projections which reach through the standards into the path of the said cams, a windlassing-rope attached at its ends to the said sliding blocks, suitable gearing for revolving said gear-wheels, F, and cams, G, and a pair of weights attached by ropes or cords attached to said weights for lifting the sliding blocks upward when the ends of the cams pass the projections 011 the said sliding blocks substantially as described.
